WINDOW.

Specification of Letters Patent.

Application filed-January 20, 1916. Serial No. 73,194.

do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to that class of windows wherein a sash is adapted to be swung to a tilted position from its normal closed, that is to say, its vertical position for the purpose of regulating ventilation and to permit the cleaning of the glass pane with safety and facility and isin the nature of an improvement upon the window forming the subject matter of my Patent Number 1,171,367, issued February 8, 1916.

While my invention is based upon the same general principles as the structure of the above named application, it difiers therefrom in certain respects so as to present material advantages over the said structure of the application. For instance, instead of employing a guide strip which is provided with an inside or resilient flange, I use a rigid channeled guide strip which provides ample space for a cam having a resilient cam finger, in the pivot of the follower, the provision of such a cam insuring a better gripping action against the sides of the channel.

In the accompanying drawings:

Fig. 2 is a detail perspective view of one side of the sash and showing the sash strip, the follower cam and the pivot-cam;

showing its position in the channeled guide strip when the sash is in one of its tilted Referring to the drawing by reference characters wherein like parts are indicated by like characters throughout the several views:

For the sake of brevity I will describe the invention as applied to the'lowersash but it is to be understood of course that it is applicable to the upper sash as well.

Referring now to the accompanying drawing in detail, the window frame is indicated by the letter A and the upper and lower sashes by the letter B. I provide, at each side of the window frame A, a longi tudinally extending metallic guide strip which is indicated as an entirety by the letter O. This strip is constructed of a single piece of metal which is bent. longitudinally to form a flat base 1 which is secured to the window frame by any suitable means. Extending from this base 1 are front and rear walls 2 andB respectively, the inner wall being termed the front wall and the outer wall, the rear wall; These walls 2 and 3 and the base 1 present smooth unbroken surfaces to form a channel while the walls are provided with flanges 4 and 5 which extend at right angles to the walls in the same direction, thewall 3 is ofgreater width than the wall 2 as clearly illustrated in Fig. 3 of the drawing for a purpose which will later become apparent. The window sash B includes usual side bars 6 and each of these side bars is rabbeted as at 7 and is provided with a longitudinally extending slot 8 at the inner end of the rabbeted portion. Secured to the outer side of each of the side bars 6 is a strip 9 which is secured to the side bar by suitable fasteners and which will hereinafter be designated as the sash strip. This strip is of equal width to that of the side bar of the sash and a portion thereofoverlies the rabbeted portion of the guide bar to form a channel as clearly illustrated in Fig. 3 of the drawing. This strip is bent to form a channel 10, at its rear edge, which channel extends longitudinally of the strip and the strip is bent back upon itself toform a lip 11 which extends into the slot. 8 in the side bar.

Secured to the lower end ofeach sash strip 9 is a pivot cam 12 which is rigid with the strip and which extends into the channel of the adjacent guide strip. The

- taining the sash in its inclined position;

cam finger 13 which is integral with the body portion and iseccentrically arranged with respect thereto. It is to be noted that when the sash is in its vertical position the to an inclined position the finger will bind against the wall 2 and thus assist in main- Thus it will be seen that the sash may be moved pivotally to an inclined position or slidably when it is in a vertical position owing to theconstruction and arrangement of the cams 12 within the guide strips.

Pivotally mounted on each of the sash strips is a link 14, the pivot points being at 15. These links extend upwardly and mounted on the upper ends thereof are cams 16 which are similar in construction to the cams 12 and which will hereinafter be designated as follower cams. These cams 16 slide in the channels of the guide strips:

in a manner similar to that -in which the cams 12 slide thereinand when the window sash is moved pivotally about the cams 12;

the fingers 17 of the cams 16 will be forced against one wall of the guide strips so as to assist in binding the sash in its tilted position. Secured to each of these, cams 16 is the inner faceof the flange will engage.

the adjacent face of the sash strip so that an absolutely weather-tight joint is pro-,\ relation to the guidesiand upon which the.

vided. Furthermore in connection with this sash. isslidable and-rotatable with respect lip 11, it is pointed out that the extension of thislip into the slot 8 prevents or tends to prevent the warping of the sash at right angles to the plane thereof. When the sash is in its vertical position, the flange 4 ex tends into the channel 10, Thus the sash may be either raised or lowered as desired It will thus be seen that Ihave provided cams on which the sash is pivoted, which cams areslidable in theguide strips and which bear against the walls thereof when the sashis swung into an inclined position to maintain the sash in ,such position. Furthermore I have provided links which are pivotally connected to the sash at points between its ends and which are provided,

with cams which likewise operate in the guide strips and bind thereagainst when the sash is tilted in an inclined position."

It willbe noted that by having the engaging faces of each cam in resilient relation' to each other, all of the cams will operateto wedge in the guides, which would not necessarily occur if the cams were not I'GSlllG-H-tyas when the guide channels might have their walls unparallel.

What I claim is 1. The combination withla window frame, of channeled guide strips. located at .the sides thereof, a vertically sliding window sash, andpivot-cams secured to the lower endsof the-sash Etl'lddTlOViLlOlB in the channels of said strips, the said cams having body portions substantially circular in formation and resilient fingers integral with,

the body portionsiand eccentric to thecenters thereof, the said fingers being adapted to bind against thewalls of the guide; strips when the-sash is swung to an lIICllIIBd'POSlc.

tion;

2." The combination with a window frame rotatably' engaging the corresponding guides and of such dimensionsas to insuremovement of them into and out of contact with thesidesof the channels, thecontact-- ing faces of the cams being in resilientrelation to each other foryielding engage,-

ment with the sides of the channel.

3. The combination with a window frame having guides, of a sash mounted .in the frame, cams carried by the sash in guiding to the guides, links connected with the engagement with'theguides when the sash .is swung pivotally, said cams being constructed for resilient engagement withthe gu des, whereby engagement of all cams is insured.
